importd: split out setup logic for /var/lib/machines into its own API file 2015-03-01 16:39:31 +01:00			`#pragma once`

shared: include what we use The next step of a general cleanup of our includes. This one mostly adds missing includes but there are a few removals as well. 2015-12-03 21:13:37 +01:00			`#include <stdint.h>`

importd: add new bus calls for importing local tar and raw images This also adds "machinectl import-raw" and "machinectl import-tar" to wrap these new bus calls. THe commands basically do for local files that "machinectl pull-raw" and friends do for remote files. 2015-03-05 00:56:08 +01:00			`/* Grow the /var/lib/machines directory after each 10MiB written */`

machined: also set up /var/lib/machines as btrfs, if "machinectl set-limit" is called 2015-03-02 19:21:04 +01:00			`int setup_machine_directory(uint64_t size, sd_bus_error *error);`
importd: automatically grow /var/lib/machines/ loopback filesystem during downloads If /var/lib/machines is mounted as btrfs loopback file system in /var/lib/machines.raw with this change we automatically grow the file system as it fills up. After each 10M we write to it during imports, we check the free disk space, and if the fill level grows beyond 66% we increase the size of the file system to 3x the fill level (thus lowering it to 33%). 2015-03-03 00:13:12 +01:00			`int grow_machine_directory(void);`
